Processing.js

This is the compilation repository for Processing.js, used in building the processing.js library from a series of Node.js flavoured commonjs modules, rather than existing as one large file as was the case in all versions up to and including 1.4.1 (released august 2012) .

Versioning

Processing.js adheres to semver style versioning, with the current version being 1.6.0 (released July 9th, 2016)

This project is currently in need of developers

There is currently no one working on, or maintaining, this codebase on a regular basis, so if you think you'd like to contribute to Processing.js, to bring it back in line with Processing's current API, and take advantage of the various APIs that have become available in browsers since Processing.js slowed down, we'd love to hear from you!

File an issue to say that you'd like to help out, and we can find some good places for you to get started.

Getting Processing.js

Bower install

bower install Processing.js

NPM install

npm install processing-js

Getting Processing.js the plain way

Simply grab the processing.js or processing.min.js files, include them as script on your webpage, and you're all set. See test.html for a simple example of using Processing.js on your pages.

Playing with the code

Clone this project using git, and ensure you have node.js installed. After cloning, install the require node packages using npm install in the processing-js directory. Modifying the code and building your own processing.js and processing.min.js files is then a fairly straight forward process. Modify the code as much as you want or need, then:

Lint: $> grunt

Test: $> node test

If step 1 gives you a "grunt: command not found" or similar error, run npm install -g grunt-cli to make sure grunt is globally installed as CLI command. If step 1 does not throw any errors, step 2 will run the Processing object through a battery of tests. Once the browser reference tests start, your processing.js and processing.min.js have been successfully built.

The test script also accepts the following optional arguments:

--test=testfile.pde runs one specific test

--nobuild does not build Pjs if all tests pass

--failonerror terminates the run if any error occurs.

--noref will not start a server process and a browser for doing ref testing.

--noautoref will start a server and a browser for ref testing, but doesn't auto-start the tests.
